<h3>User Interface</h3>

<p>
    The Land/Water Mask processor can be invoked in the Sentinel Toolbox from tool menu by selecting
    <b>Raster->Mask->Land/Water Mask</b>.
    On the command line the Land/Water Mask processor is available by means of the Graph Processing Tool <code>gpt</code>
    which is located in the Sentinel Toolbox <code>bin</code> directory.
    Typing <code>gpt LandWaterMask -h</code> displays further information.
</p>

<h4>I/O Parameters Panel</h4>

<h5>Source Product Group</h5>

<p class="i1">
    <b>Source product:</b>
    Here the user specifies the source product.
    The combo box presents a list of all products opened in the SNAP.
    The user may select one of these or, by clicking on the button next to the combo box, choose a product
    from the file system.
</p>

<h5>Target Product Group</h5>

<p class="i1">
    <b>Name:</b>
    Used to specify the name of the target product.
</p>

<p class="i1">
    <b>Save as:</b>
    Used to specify whether the target product should be saved to the file system. The
    combo box presents a list of available file formats.
    The text field or the button next to it allow to specify a target directory.
</p>

<p class="i1">
    <b>Open in SNAP:</b>
    Used to specify whether the target product should be opened in SNAP.
    When the target product is not saved, it is opened in SNAP automatically.
</p>

<h4>Processing Parameters Panel</h4>
<p align="center"><img src="images/LandWaterMaskProcParameters.png" alt="Processing Parameters of LandWaterMask Processor"></p>

<p class="i1">
    <b>Resolution:</b> Select one of the available resolutions from the predefined list.
    Defines the resolution and the origin of the source land/water map. Available resolutions are 50 meter,
    150 meter and 1000 meter per pixel. For more explanation on the source data see the
    <a href="WatermaskAlgorithmSpecification.html">Land/Water Mask Algorithm Specification</a>
</p>

<p class="i1">
    <b>Subsampling factor x:</b>
    Specifies in how many sub-pixel each pixel of the input is sub-sampled in x-direction. A value of '1' means no sub-sampling at all.
</p>

<p class="i1">
    <b>Subsampling factor y:</b>
    Specifies in how many sub-pixel each pixel of the input is sub-sampled in y-direction. A value of '1' means no sub-sampling at all.
